If the buy isnt urgent, Wait for the new Civic now, last year Altis had a facelift was new, This year iguess you should wait for the new Civic, If its urgent, Go ahead, Its a nice buy, Do check with Honda maybe you get some clearence discounts.
colour should be your choice,
by worth it what do you actualy mean? Because you dont get anything brandnew in that price range. The other stuff is Japanese Used, Yes they can be better but that is if you dont mind getting a used Japanese car.
